This invention relates to dynamic devices for insulating wall surfaces and especially surfaces including a window. A self-inflating solar curtain is automatically raised and lowered in response to the direction of heat flow into or out of a confined space within which the temperature is to be controlled. This confined space could be a solar collector, a room in a house, or other enclosure requiring temperature control. The curtain comprises at least one double-walled air-entraining envelope with vents for enabling an inhaling or exhaling process which takes air into and expells air from the envelope as the curtain is heated or raised, respectively. The curtain can be wound upon and stowed on a roller driven by a motor or other suitable means which may be controlled automatically by sensors which detect and respond to temperature differentials on opposite sides of the curtain.

A dynamic process for insulating an interior side of a surface, said process comprising the steps of: (a) implacing or removing a curtain, including an entrapped air space, in a position adjacent a side of said surface which is to be insulated responsive to sensed temperatures in the area of the surface; (b) self-inflating said curtain means, including said entrapped air space, through at least one opening near the bottom thereof responsive to expansion or contraction of air in the air space of the curtain as ambient temperature heats or cools the surrounding area; so that any air entrapped therein rises within said curtain responsive to a heating of said entrapped air by increases in temperatures adjacent said curtain, the heated air expanding the volume of said air space whereby fresh air is drawn through said opening by an inhalation process.
